IMPROVEMENT IN CLOTH-PRESS.

To all whom it may concern:

Be itknown that we, 0. H. WESTON and J orm DEN- NIS, of Lowell, iuthe county of Middlesex, and in the State of Massachusetts, have invented a certain new and useful Improvement in ;Hollow Steam-Press Plates, with their corrections; and do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon,

This invention relates to that class of presses in which the several pieces of folded cloth to be pressed are placed betweeum etallic plates, arranged one above the other, each plate being internally heated by steam, or otherwise, and having conducting-pipes, to permit the pressure upward otthe plates, by means of an bydraulic rain, or pump; and

It consists-in, fiist, the means of raising any indicated plate separately, so as to increase the space for the insertion of the fabric; second the arrangement of the inside of the plates, whereby the plhtes are heated very quick, the steam passing through easier than in any plates now in use, and also not being so liable to be strained or leak on the. goods third, the steam-box, and the manner of connecting the pipes to it; fourth,

the stands on which the plates rest.

In order to enable others skilled in the art to which our invention appertains, to make and use the same, we will now proceed to describe its construction and operation, referring to the annexed drawings, which form a part of this specification, and in which- Figure 1 is a rear elevation of the machine, showing the steain box and connecting-pipes;

Figure 2 is an inside view of the plate, showing the various channels through which the steam passes; and

Figure?) is a side view of the press.

A represents the frame of a steam-press, at the lower end of the rear side of which is placed the steambox B, the peculiar construction of which is seen in fig. 1.

A partition, 0, divides the steam-box into two chambers.

The steam entering one of those chambers, is carried, through pipes I) D, into the plates E E, thence out through similar pipes to the other chamber of the steam-box.

The pipes are so arranged that, passing through packingboxes F F, on top of the stearmbox B, they are raised or lowered with the plates E E, in conformity with the action of the steam on said plates.

' It will be seen that we use only two pipes to each plate, to convey the steam and water in and out.

The packing is put into the sim le box F, on top of the steam-box B, and the pipe war in the box, making a safe and sure packing.

The shape of the steam-box B, as shown in fig. 1, allows the condensed water to run away with great case, which is absolutely necessary, as, if water remains in the same. it causes a strain throughout the whole machine.

The plates E E are hollow, and their inner sides provided with a series of bars, a a, as shown in fig. 2, forming channels for the steam to pass through acting upon the whole inner surfaces of the plate.

It will be seen that the bars a a are so arranged as to be at. right angizs with the sides, and form a single passage for the s m to pass though, and that they are, further so placed that the steamacts upon the largest possible surface with the smallest possible number of turns.

The corners of the bars (m are shown as being square, but we prefer romiding them, as steam and water will more, easily pass a round corner than a square one;

and the chainiel through which the steam and water have to pass is soar-ranged that the steam is sent around the outside of the plate first, as shown in fig. 2, byred arrows. I

By this arran ement of the bars a a, the plates heat much quicker, t e steam passes through easier, and is not so liable to strain the plates and leak on the goods, In like manner, when, the steam is stopped, the water goes through much quicker and easier, cooling the plates in the short-est possible time.

They are further provided on their ends with lugs b b, which rest on and work in the stands GVG,OI18 on each end of the frame 'A These stands, as shownin fig. 3, form akind of stairstep arrangement, in which the plates-work up and down, each plate having its own step om-vlimh itcrests.

On top of the press are pivoted two levers, ELI-I, which meet at the centre, and theiroutcr ends extend beyond the ends of the press, these ends of the levers being forked and surrounding the upper ends of the shafts I I, which are placed perpendicularly in sockets or loops, on the ends of the press, for theipnrpose of raising each of the plates squaratelyfif desired, to give more room to insert the goods which are to be pressed.

The shafts I I are provided with dogs J J, which can be a 'usted at height desired, y means of screws 41 holding them on said shafts.

Slides K K are then placed on the dogs J J, under the plate which is to be raised.

Across the upper end of the press, a shaft, L, is placed, in suitable hearings, which is provided with a cam-wheel, M, on its centre, working on the inner ends of the levers H H, and a wheel, N, atits end, this wheel being provided with ropes and weights, or other suitable arrangement, to be turned in either direction.

It will be seen that, by turning the shaft L, by means of the wheel N, the oam-wheel M presses the inner ends of the levers H H down, raising the outer forked ends, and with them the shafts I I.

The dogs J J and slides K K being first placed in proper position on said shafts, will, of course, raise any plate desired.

Having thus fully described our invention,

What we claim as new, and desire to secure by Let-- ters Patent, is-

1. The shafis I I, provided with adjustable dogs J J and slides K K, in combination with the levers H H,

shaft L, cam-wheel M, and wheel N, all arranged as described, and operating for the pnrpose of raising any indicated plate separately, substantially as herein set forth.

2., The arrangement of the steam-box B, packingboxes 13 F, and pipes D I), snbstantiallyas shown and' described. v

3. The stationary stands G G, constructed asldescribed, with'stair-steps, on which the lugs b b, on the plates E E, rest, substantially as herein set forth.

In testimony that we claim the tbregoing, we have hereunto set our hands, this 18th day of July, 1868.
